I have a Turnaire with the chariot. I weigh 215lbs and it works great and saves lots of time on flat ground. It has trouble pulling any type of hill with me on the chariot. I usually hop off and walk the hill and then hop back on when flat again.

Ditto, I'm about 245. You learn the feel when it starts to bog. I usually just step off and maybe even push with the foot I step off with. Since buying my Exmark, I'm keeping my Turfco for small gated backyards. Free bump for a great machine.
